The openings E in the walls a may, howeve, be closed in any manner other than by blocks if desired, us by doors.

The location. of the receptacle centrally of the casing and spaced therefrom forms heating areas around all parts of the former, including a transversely curved space L at the bottom, vertical spaces Z at the sides, spaces Z at the ends, and Z at the top.

Heat may be supplied by any means preferred. in the present instance it is furnished by gas, and is supplied by an air supply pipe N and a gas supply pipe M converging a mixing chamber is. From chamber 02 extend brench pipes O and O exterior of and parallel With the sides of the casing, having respectively two in- Wardly directed branch pipes P and P, termineting in burners Q", end'Q res ectively, disposed horizontally in opposite irections, and extending through openings 9 and g respectively in the lower portion of the casing into the space L. Upon the pipes P and F respectively are bearing plates it and B respectively contacting with the exterior of the casing. It has been found adventegeous, but not essential, as shown in Fig. 5 to have the burners Q and Q disposed diagonally rsther than directly opposits each other.

The arrows in Figs. and 4 show the course of the heat from'theof the burners, around the bottom, top, sides, and ends of the receptacle. The heat passing through the spaces Z around the extensions 3 communicates itself to the plugs K so as to supply heat also at both ends of the chamber G. The wall a is provided with.

an opening S, closeble by a plug 8, to give access to the burners. The receptacle F is filled with a fusible metal, or a combination of fusible salts, T, preferably lead, which metal or salt will be fused by the heat when the heat is applied as described. The fused salts are advantageous for producing temperatures from 300 to 600 degrees, while lead produces temperatures to 1800 degrees Fahrenheit and higher.

In operation one of the plugs K is menually removed, and the article to be tempercd, soldered, or otherwise treated is placed in the Chamber G, where its temperature is raised uniformly in every part, even at its top, because of the uniformity of the degree of heat in every part of the chamber, due particularly to the presence around four sides of the chamber throughout its length of the fused mass T througlbut which the heat is uniform. This muss ulso retains its heat Without dissipation fora long While after the flame is shut off. will furthe be understood therefrom, for obvious modil cations will occur to a person skilled in the e'rt.

, What I claim is,

1. In an apparatus for raising the temperature of articles, the combination of a casing, u receptacle in said busing and spaced therefrom, a housing in said receptacle provided with portions extending-through tit casing, said receptacle adapted to receive fusiole material surrounding the housing and a removable closure for an end of the housing.

2. In an apparatus for raising the tee pcreture of articles, the combination of e casing, a receptacle in said cosin and spetherefrom, a housing in said receptacle provided with portions e tending through th casing, said receptacle adapted to recei r fusible material surrounding the housing,

a removable closure for on end of the housn g,

and oppositely disposed heating means in the casing beneath said rcceptac e.

3. In an apparatus for raising the temperature of articles, the combination of u casing comprising a bottom, vertical side walls, end walls, and a cover, said end walls being provided with openings, a receptacle in the cesing end spaced therefrom, a housing extending transversely of the receptacle rovided with open end portions extending into said openings and forming supports for the receptacle, closure members for the extending portions of the housing, and burners in the casing below the receptacle.

4-. In an apparatus for raising the tem pcruturc of articles, the combination of a receptacle, housing traversing the receptacle and provided with extended open end portions, a casing surrounding the receptnclc and provided with openings to receive the cud portions of the housing, means for closing the end portions, and burners in the casing adjacent the receptacle.

5. in an apparatus for raising the temperature of articles, the combination of u re'ccptu'clc provided With ELCUI'VQdbOttOHl portion and with an open top, a casing sin rounding the receptacle having openings in its sides and provided with a curved portion adjacent the curved portion of the receptacle, suid receptacle and easing being spaced from each other at all points, oppositely disposed burners in the curved portion of the casing, and a housing, in the receptacle extending into the openings in the casing.

with nycnings to m ivc the 0nd portinm,

m1 burners in the ncle.

In testimony whereof I have aifixed my ignature in presence of two WilHBSSGS.
